Study Notes
Cellular Structure and Function
- Living cells differ from non-living cells because they are capable of maintaining homeostasis, regulating their environment, and reproducing.
Organelle Function
- The organelle shown in the figure is the mitochondrion, and one of its main functions is to generate energy for the cell through cellular respiration.
Prokaryotic vs. Eukaryotic Cells
- The defining property that differentiates prokaryotic cells from eukaryotic cells is the presence of a true nucleus in eukaryotic cells.
Cell Type Characteristics
- The cell type that has a long, branched structure that requires many connections to be made with neighboring cells is the neuron.
Nucleus Function
- The main function of the nucleus is to control cell growth and division by storing and regulating genetic information.
Cellular Process
- The cellular process by which vesicles are secreted from cells is called exocytosis.
Cell Component Identification
- The cell component indicated in the figure by the line labeled as number "3" (green) is the ribosome.
Mitochondrial Structure
- The inner membrane of the mitochondrion when examined with transmission electron microscopy appears folded into a series of cristae.
Prokaryotic Classification
- Archaea and bacteria are both prokaryotes, but they distinguish themselves by their cell wall composition, with archaea having a unique cell wall lacking peptidoglycan.
Universal Cellular Properties
- All living cells are capable of responding to stimuli, adapting to their environment, and maintaining homeostasis.
